Due to its environmental protection and wide temperature range, rubber seals can be used for a long time within the temperature range of -60 ℃ ~+200 ℃, so they are used more and more widely, such as lunch boxes, water cups, rice cookers, water dispensers, incubators, ovens, ovens, coffee
Due to its environmental protection and wide temperature range, rubber seals can be used for a long time within the temperature range of -60 ℃ ~+200 ℃, so they are used more and more widely, such as waterproof sealing of lunch boxes, water cups, rice cookers, water dispensers, incubators, ovens, coffee pots and other daily necessities. What are the advantages and disadvantages of silicone seals?
I. advantages of silicone seal ring and rubber seal
1. Good sealing performance, waterproof and non-toxic;
2. It can be heated under high temperature without deformation and harmful substances;
3. Good tensile resistance;
4. It will not fade without yellowing after long-term use;
5. Corona resistance, arc resistance, high and low temperature resistance, aging resistance and high temperature resistance;
6. Good heat resistance. The silicone sealing ring can be used for a long time at 150 ° C without performance change. It can be used continuously for 10000 hours at 200 ° C and temporarily at 250 ° C;
7. Silica gel sealing ring has good cold resistance. Ordinary rubber is generally - 20 ℃ - 30 ℃, while silica gel sealing ring still has good elasticity at - 50 ℃ - 60 ℃. Some special low temperature resistant silica gel can also withstand lower temperatures.
